  • the width and the breadth and the distance of the top wall 70 from the second means for aerating 2 define a fourth compartment 500 in which smoke gas may be exposed to a cleaning device(8), if desired.
  • the dashed lines symbolize the position of ash grate 3 and first and second means for aerating 2.
  • the relative position of ash grate 3 and first means for aerating 1 and second means for aerating 2 is crucial for the efficacy of the fireplace according to the invention.
  • This efficacy may be further improved by means of third means for aerating 30 and fourth means 40 for aerating (also indicated be dashed lines).
  • the third means for aerating 30 is arranged such to feed combustion air to furnace door 4.
  • Fourth means for aerating 40 is arranged below ash grate 3 in order to further support the burning of combustible when operating the fireplace according to the invention.
